Spike’s ST-T2 Heavy Buffer

The ST-T2 buffer is one of the softest shooting, smoothest, and quietest buffers on the market; not to mention it looks awesome! It doesn’t have any weights to move around or fluids to leak out like some other buffers, so it’s 100% maintenance free!

The ST-T2 buffer weighs in at 115g/4.05oz. (Depending on the density and size of the HDTP, the weight can vary slightly) and the body is CNC machined from solid billet Aluminum bar stock for strength and durability. To finish it all off, it’s Anodized matte black and laser engraved with our Logo.Each ST-T2 buffer is filled with HDTP which is short for “High Density Tungsten Powder” and topped off with a Mil-Spec bumper. Because of this, there aren’t any reciprocating weights inside to make a lot of noise and it also makes for a very smooth cycling rifle. The ST-T2 eliminates the chance of bolt bounce, helps with muzzle rise when firing in full-auto, and cuts down on felt recoil. As you can tell, it’s a HUGE upgrade from a Standard Carbine buffer! It’s designed for .223/5.56 but it works in all Calibers!
